Bailey - Chief Engineer} Rm{William Robotham - Chief Engineer}/Les2/R.6.11.36. Visibility from the Driver's Seat P.III. It has been suggested that the difficulty to see the road from the Driver's seat is due to the front of the car being high relative to the rear of the car. With the experimental cars, and we see no reason why the first production cars should not be similar, the actual condition is reversed, that is, the front of the cars are slightly low compared to the rear of the car, as designed. In order to lower the front of the car and retain adequate ground clearance and wheel movement, considerable alterations would be required. We suggest as a means of getting and immediate improvement the front spring poundage should not exceed 1250 lbs, but that the poundage of the rear springs should be increased by 50 lbs.
